Title: Image forming device
Inventor: YANAGIDA MAKOTO
IPC: G03G15/00
Filed: 1991-10-31
Abstract: PURPOSE:To steadily form an electrostatic latent image, which is faithful to the image of an original, at all times by controlling exposure provided by an exposure device, according to the shave of the surface layer of the photosensitive layer of a photosensitive drum surface. CONSTITUTION:An electrification bias applying means 29 applies an electrification bias, in which an AC element overlaps an DC element, to a conductive rubber roller 25. When the surface layer of the photosensitive layer on the surface of the photosensitive drum 1 is shaved, the DC element of the electrification bias is increased. The DC element of the electrification bias is detected by a DC current detecting device 30. Based on the predetermined specific relationship, an exposure controlling device 31 controls the exposure provided by the exposure device A. Thus, the light potential of the surface of the photosensitive drum 1 always becomes stable.
